20100237970 | MAGNETIC LOCKING SYSTEM - Preferred embodiments of the present magnetic locking system can be used for releasably locking a first component to a second component. In one embodiment, the locking system includes a ferro-magnetic member associated with the first component, where the ferro-magnetic member is made of a ferro-magnetic material, and a housing attached to the second component and positioned adjacent to the ferro-magnetic member. Preferably, the housing includes first and second blocks that sandwich an intermediate block. Further, the first and second blocks are each preferably made of a ferro-magnetic material and the intermediate block is made of a non-ferro-magnetic material. Additionally, there is also an aperture formed within the housing, with a permanent magnet rotatably seated within the aperture. The magnetic locking system preferably includes a switch mechanism that is operatively connected to one of the permanent magnet and the housing, wherein the switch mechanism is configured and arranged to rotate the housing and the permanent magnet relative to each other between an “on” position and an “off” position. | 09-23-2010 |
20110303065 | LOCKING CONSTRUCTION FOR A MITER SAW HAVING A HINGED LINEAR GUIDE MECHANISM - Embodiments of a power miter saw comprise a saw base, a rotatable table, a miter arm, a saw blade and motor assembly operatively connected to the table, a hinged linear guide mechanism configured to support and move the assembly along a predetermined linear path, the mechanism comprising a first hinge having first and second links pivotably connected together by a first shaft extending through aligned openings therein, and a locking lever having a handle and a locking blade at opposite end portions and a pivot portion with a pivot connection therebetween for pivotably mounting the lever to one of the links, the blade being configured to fit within a gap between adjacent surfaces of the first and second links when the guide mechanism is in one of its extended or retracted positions and the lever is moved into a locked position. | 12-15-2011 |
20120011978 | GLIDE MOVEMENT CONTROLLER AND POWER MITER SAW INCLUDING SUCH CONTROLLER - A glide movement controller for use with a hinge connection that includes a shaft, as well as a hinge connection and a power saw including such a controller. The glide movement controller includes a generally U-shaped controller body configured to move towards the shaft in a first direction such that resistance upon the shaft is increased and away from the shaft in a second direction such that resistance upon the shaft is decreased; a pair of apertures extending through the controller body; and an interior bearing surface defined on the controller body. The interior bearing surface is configured and arranged to face the shaft. In certain embodiments, at least a portion of the interior bearing surface is located between the apertures. | 01-19-2012 |
20120017736 | POWER CORD ROUTING SYSTEM FOR MITER SAW WITH HINGE LINKAGE LINEAR GUIDE - A power saw includes a table configured to receive a workpiece, a saw blade and motor assembly having a motor for rotating a saw blade, and a power cord connected to the motor for supplying electric power to the motor. A linear guide mechanism is operatively connected to the table and is configured to pivotally support the saw blade and motor assembly. The linear guide mechanism enables movement of the saw blade and motor assembly along a predetermined linear path in a forward or a rearward direction, and includes at least two links connected by a hinge connection. A cord clip is rotatably fixed to the hinge connection and configured to receive a section of the power cord. | 01-26-2012 |
20120017737 | LOCKING MECHANISM FOR MITER SAW WITH HINGE LINKAGE LINEAR GUIDE - A power saw includes a table configured to receive a workpiece, a saw blade and motor assembly, and a linear guide mechanism operatively connected to the table and being configured to pivotally support the saw blade and motor assembly. The linear guide mechanism enables movement of the saw blade and motor assembly along a predetermined linear path in a forward or a rearward direction at a constant level, and includes a first link and a second link pivotally connected by a first hinge connection. The first and second links enable the linear guide mechanism to maintain the saw blade and motor assembly at the constant level. The power saw further includes a locking mechanism which is fixed to the first hinge connection for locking the linear guide mechanism to prevent the saw blade and motor assembly from being moved along the predetermined linear path. | 01-26-2012 |
20140020919 | Collet Fan for a Rotary Tool - A rotary tool includes a motor having an output shaft, the output shaft defining an axis of rotation. The motor is configured to rotate the output shaft in a first direction about the axis of rotation. An accessory tool retention mechanism is attached to a distal end portion of the output shaft and configured to releasably retain an accessory tool in alignment with the axis of rotation. A fan mechanism includes a plurality of fan blades attached to the accessory tool retention mechanism and extending radially outwardly therefrom. The plurality of fan blades are configured to move air forwardly in a direction that is generally parallel to the axis of rotation as the accessory tool retention mechanism is rotated in the first direction by the output shaft. | 01-23-2014 |
